Answer:
116°
Explanation:
There are 2 right angles so we add them:
1 right angle = 90°
2 right angle: 90° + 90° = 180°
As we can we have another value which is 64° so we add that as well:
180° + 64° = 244°
Since it is a 4-sided shape all the values will add up to 360°
Subtract 360 and 244
360° - 244° = 116°
x = 116°
Hope this helps
